 Yacc expansion of optional clause using the same keyword as following clause

wish of those help By themselves, the above rules don't cause any problems; yacc/bison can handle them just fine with no shift/reduce or reduce/reduce conflicts. Where you might be getting into problems is if start is also a legal expression. If that's the case, the language is ambiguous -- when you have a start within a start, a WHERE might be associated with either one. For example, the input code :
START RETURN START RETURN expr WHERE expr RETURN expr
START RETURN ( START RETURN expr ) WHERE expr RETURN expr
START RETURN ( START RETURN expr WHERE expr RETURN expr )

This might help you Your conditions when you got client and search are not correctly grouped code :
Contact::when($request->client && $request->search, function ($q) use($request) {
$q->whereHas('companies', function ($q) use ($request) {
$q->where('is_client', true);
})->where(function ($q) use ($request) {
$q->where('first_name', 'like', '%'.$request->search.'%')
->orWhere('last_name', 'like', '%'.$request->search.'%')
->orWhereHas('companies', function ($q) use ($request) {
$q->where('name', 'like', '%' . $request->search . '%');
});
});
})->when($request->client == null && $request->search, function ($q) use($request) {
$q->where('first_name', 'like', '%'.$request->search.'%')
->orWhere('last_name', 'like', '%'.$request->search.'%')
->orWhereHas('companies', function ($q) use ($request) {
$q->where('name', 'like', '%' . $request->search . '%');
});
})->when($request->client && $request->search == null, function ($q) use ($request) {
$q->whereHas('companies', function ($q) use ($request) {
$q->where('is_client', true);
});
})
->paginate(30)
$contactQuery = Contact::query();
if ($request->client) {
$contactQuery->whereHas('companies', function ($q) {
$q->where('is_client', true);
});
}
if ($request->search) {
$contactQuery->where(function ($q) use ($request) {
$q->where('first_name', 'like', '%'.$request->search.'%')
->orWhere('last_name', 'like', '%'.$request->search.'%')
->orWhereHas('companies', function ($q) use ($request) {
$q->where('name', 'like', '%' . $request->search . '%');
});
});
}
$contacts = $contactQuery->paginate(30);

Laravel 4: optional wherein clause
By : Sivasankari Kesavan
Date : March 29 2020, 07:55 AM
seems to work fine Basically I have a routing system in Laravel that passes on an optional high level tag name which is used to retrieve a list of tags from a database collection (I am using MongoDB) and use that tag list in turn to retrieve data from another collection. , That's what you're looking for:
